Inventor: PETTERS OSCAR RICHARD
IPC: G04B33/10
Filed: 1960-09-02
Abstract: 928,731. Watches. PRECISION TIME CORPORATION. Sept. 2, 1960, No. 30416/60. Class 139. In a watch the frame comprises two spaced plates, each having different levels. The dial plate 27, Fig. 1a has three levels 28, 29, 30 and the top plate 56 has a depending lug 96 to receive the upper jewel of the escape lever arber. The levels 28 and 30 are joined along curved lines across the plate 27. A centre seconds hand 46 is provided. A block 120, Fig. 16, located between the plates 27, 56 has two extending arms which embrace the pinion 127 on the winding stem 125. The pinion 127 meshes with a winding wheel 133, Fig. 12, which is carried by a pivoted lever 136 and which normally meshes with the barrel ratchet 72 which is positioned above the plate 56 and is prevented from reverse rotation by a projection of a detent loaded by a spring 105 one end of which rests on the centre seconds spindle 47, Fig. 1a. A pin 142, Fig. 12, depends from the lever 136 into an arcuate slot in a pivoted setting lever 145. If the stem 125 is rotated backwards the reaction of the gear 72 on the wheel 133 causes the latter to move out of engagement therewith. An extension 150 of the setting lever 145 co-operates with a cam 152 on the stem 125 so that as the stem 125 is pulled outwardly to an extent determined by a lug 153 on the plate 56, the lever 145 is moved to bring the setting wheel into engagement with the intermediate wheel 158 which meshes with the minute wheel 36.

Title: Improvements in or relating to pear centering and feeding devices for pear processing machines
IPC: A23N4/14
Filed: 1966-07-11
Abstract: 1,081,309. Pear-processing machines. ATLAS PACIFIC ENGINEERING CO. July 11, 1966 [July 22, 1965], No. 30988/66. Heading A4C. In a centering and feeding device for a pear processing machine, e.g. of the type disclosed in Specifications 924,366 and 924,367, the pear gripping fingers are normally spring-biased outwardly and are moved inwardly to grip the pear by fluid actuated means, e.g. air, water or oil actuated means. In Fig. 2 the device 6 is pivotally mounted by shafts (44), 46 in trunnions (40, 42) on a frame 7 mounted on slides 10 attached to cross-bar 14 which moves towards and away from the pear impaling and processing structures. The stem end of a pear is placed in cone 56 when the device is in the vertical position and air is then admitted by a cam-controlled valve through a passage in pivot (44) having a narrow orifice therein to a cylinder fitted with a flexible diaphragm 54 to operate piston 52. This bears on rollers (90), 92 mounted on levers 82 and 84 respectively bolted to arms 78, 80 of yokes 70, 76 pivoted in bosses 66, 68, each yoke carrying two gripping fingers 72, 74, and biased outwardly by springs 94, 96. Adjusting screws 86, 88 are provided for centering the gripping fingers. In an alternative embodiment, three independent gripping fingers may be used. The feeding cup 6 is normally biased by a clock spring on shaft (44) to the horizontal position determined by adjustable stop 138. It is tilted to the vertical position when cross-bar 14 is withdrawn from the impaling structure by means of cam follower roller (132) attached to a crank arm (130) on the shaft 46 in contact with a J-shaped hook cam (134) (Fig. 3, not shown). The cone 56 is removably mounted on frame 7 by a quick-change feature (Fig. 5, not shown). Cone 56 has a pair of ears (112) extending sideways therefrom, each ear having a hole (114) with a slot (116) leading sideways thereto. The upper surface of the holes (114) are countersunk to mate with downwardly spring-biased cones (120) sliding on studs (122) on frame 7, so that the cap may be fitted or removed by a turning movement.
Patent GB-962605-A (GB)
Title: Shutter for photographic camera
IPC: G03B9/22
Filed: 1962-08-14
Abstract: 962,605. Camera shutters. ALFRED GAUTHIER G.m.b.H. Aug. 14, 1962 [Sept. 16, 1961], No. 31077/62. Heading G2A. A shutter having a driving member which is movable into engagement, by means of a tensioning and release mechanism, with a blade-actuating member, is characterized in that a locking member locks the blade-actuating member in the initial (shutter closed) position, and is moved out of said locking position by engagement by the tensioning and release mechanism after the latter has engaged with and then disengaged from the driving member. The mechanism is shown in its inoperative position in Fig. 1. The shutter blade actuating member is a lever 4, pivoted on a spindle 3, and biased clockwise by a spring 8 into the rest position shown. This actuates a pair of shutter blades 5 (only one shown), seen in closed position in Fig. 1. The driving member is a lever 10, pivoted at 11, and biased anti-clockwise by a spring 12. The locking member is a lever 16, pivoted at 17, and biased anti-clockwise by a spring 18 so as to bear against a fixed stop 19; in this position, the locking lever engages against an arm 4b of lever 4, so locking the latter against anti-clockwise (i.e. shutter-actuating) movement. When the tension and release lever 13 is pressed from the starting position of Fig. 1, it turns anti-clockwise on its pivot 14. A bent lug portion 13c engages against a bent portion of driving lever 10, swinging the latter clockwise, and so tensioning its driving spring 12. An arm 10a of lever 10 rides up and over a bevelled lug 4a on lever 4, finally falling behind it (position of Fig. 2, not shown). As lever 13 is pressed further, it disengages from driving lever 10, so that the latter is released to move under the action of its spring 12. Arm 10a bears against lug 4a of lever 4, and would tilt it anticlockwise except that it is still locked against such movement by lever 16. Still further depression of lever 13 brings lug 13c into engagement with the end 16d of lever 16, swinging it clockwise so that its other end 16a disengages from arm 4b of lever 4. Lever 4 is thus released to pivot anticlockwise under the action of driving lever 10, thus causing shutter blade 5, to which it is linked, to turn on its pivot 6 to the "open" position (Fig. 3, not shown). As lever 4 so pivots, it disengages from lever 10, so that both levers 10 and 4 are freed to return to their rest positions of Fig. 1; lever 4, in so returning, causes the shutter blades to pivot once more into their "closed" position. By this means the shutter blades are not actuated until after engagement between the tensioning and release lever 13 and the blade actuating member 4 has been terminated.

A cigar-wrapping mechanism has a tucking needle 3 slidingly journalled in a guiding sleeve 4 which is reciprocably movable in the longitudinal direction of the cigar bunch B and which is provided with a free end directed obliquely against the end of the bunch. The needle 3 is journalled in an opening 40 formed in a bushing 5 on the free end of the guiding sleeve 4. The needle is attached to a stem 6 and can be moved from the position shown in Fig. 1 to that shown in Fig. 3 by means of a cam-operated lever 20. The guiding sleeve 4 is attached to a sliding sleeve 7 journalled in bearings 8 in a frame 9 and movable toward and away from the cigar bunch B by means of a second camoperated lever 14. The cams operating levers 20 and 14 are mounted on a shaft 11 journalled in the frame 9. Shaft 11 also carries a cam 25 which reciprocates an arm 24 for imparting rotary movement to the sliding sleeve 7. In operation, the needle is first moved out of the sleeve 4, the needle and sleeve then being both moved to engage a bunch B. The needle is rotated through about 1.5 to 2 revolutions by the arm 24 in the same direction and with the same velocity as the bunch B.

[Also in Division G4] A valve assembly for use in a digital to analogue converter has a series of valves, the port areas of which form a binary progression. Each valve consists of a member 20 with closure members 21, 22, the position of the valve relative to the valve body 1 being adjustable by a screw 30. The valve body 1 is discshaped and has cavities 5, 7, 8 which are provided with stiffening members 9 and are connected with the inlet and outlet ports 4, 6. The valve body 1 is also provided with cylindrical channels in each of which are two stiffening rings 101 and end pieces 103, 104, clamped together by bolts. The lower end 29 of each valve stem is triangular in cross-section to centre it in the end piece 103. The upper end of the valve stem forms the core 40 of an electromagnet formed by a cylindrical sleeve 42 around which is an actuating coil. The sleeve 42 is made of a magnetic material apart from a non-magnetic ring 42<SP>1</SP>, Fig. 2 (not shown). The magnetic circuit is completed by a ring 46, external columns 48 and an end plate 49. In a second embodiment, Fig. 3b (not shown), the ring 46 is adjacent the core 40 at all times during its movement and the end plate 4a is spaced from the non-magnetic part of the sleeve by a larger magnetic end piece 41. This is stated to prevent magnetic saturation of the sleeve 42. The supply circuit for the actuating coils is described with reference to Fig. 6 (not shown). A switch which is controlled according to the corresponding binary digit is in series with a D.C. source and the coil. The latter is shunted by an adjustable resistor and a unidirectional diode. Adjusting the value of the resistor will vary the time lag of the corresponding valve, and so all the valves can be set to operate at the same moment.
